Alleged Serial Robber Caught on Camera

In video obtained exclusively by NBC 5, it shows the store clerk fighting back with his own gun.

It happened at Lisa's Beer and Wine on North Westmoreland.

Police said around 9 o'clock on Monday night, Grimble walked in with a chrome gun, demanded cash and cigarettes and ran out. The clerk ran after him with his gun.

The video also shows the suspect rip off his sweatshirt and throw money on the ground, before the clerk let him go.

At the Shell police say he robbed in Irving, the manager says he's relieved.

"I love it to death, Irving police did their job," said David Marsalis.

On Thursday, his co-worker helped police connect Grimble to the gas station robbery.

"She went down there and identified the guy, it just makes it all that more simple," said Marsalis. "She called me after she got through, she told me 'I got a little bit scared when I got down there,' but she's going to be fine; she's a tough cookie."

Grimble's bond is set at a $100,000, but that may change with the pending charges. NBC 5 checked to see if he had a criminal record. He didn't, that is, until now.
